The Speed Bounds on Event Reporting in Mobile Sensor Networks with Energy Constraints

Ensuring timely delivery of event reports is a critical requirement in mobile sensor networks, as the effectiveness of area surveillance depends largely on the sensor network response delay. However, due to the sensor mobility and the energy limitation, fast report transportation is constrained by the intermittent wireless link connections between sensor nodes. We derive lower and upper analytical bounds to characterize quantitatively the event reporting speed by considering both the sensor mobility and the energy consumption. Our work evaluates the delay performance of mobile sensor networks to meet the prompt reporting requirement in these networks.
